After a few sets of no less than 15 reps on the squat and the same again on the leg press it was time to up the ante and really put my quads to the test. So I supersetted with 3 sets of the hack squat with a narrow stance (to bring out my outer sweep development) immediately followed by dumbbell lunges (leaning forward to place more emphasis on quads rather than hips). Give it a go for an insane quad pump and to test your ability to handle pain!
